Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare destructiveHint=true, readOnlyHint=false and openWorldHint=true, so the safety profile is known; the description goes beyond them by stating what actually happens ('writes the suggested content to the target Space document and marks the suggestion applied') and that authorization is required. It stops short of describing reversibility or what happens on a failed/unauthorized apply.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Three short sentences, front-loaded with the trigger condition, then the behavioral warning, then the prerequisite. No filler, though the destructive warning and the 'apply or accept' pairing are mildly redundant with the annotations.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a single-parameter mutation with no output schema, the description covers the trigger, the side effects, the authorization requirement, and the prerequisite tool. The only gap is that it says nothing about what the caller receives back or what happens if the suggestion is stale or already applied.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With one parameter at 100% schema coverage the baseline is 3, but the description adds provenance the schema lacks: it tells the agent the suggestion_id must be obtained from list-space-suggestions rather than guessed. It adds no format or validation detail beyond that.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb pair ('apply or accept') and resource ('one pending Autopilot/repository-sync documentation suggestion'), with the scope qualifier 'one' that separates it from bulk-manage-space-suggestions. An agent can distinguish it from discard-space-suggestion and snooze-space-suggestion without opening any schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly gives the trigger condition ('when the user wants to apply or accept one pending... suggestion') and names the source of the required input ('Requires suggestion_id from list-space-suggestions'). It does not explicitly exclude alternatives such as bulk-manage-space-suggestions for multiple suggestions, but the singular scope makes that inference safe.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
